17 Claims.

This invention relates to improvements in car dumpers.

Its object is to provide a simple and eflicient arrangement of a self-propelled vehicle, such as a mining locomotive, provided with a vertically pivoted overhanging structure for raising, laterally moving and dumping flat cars.

Another object is to provide a mechanism for moving a pair of lifting rods which clear the sides lo of the car to be elevated when below the edges of such sides and to move these rods inwardly under the sides of the car as they are raised.

Another object is to mount the hoisting mechanism on a frame horizontally pivoted on the overhanging structure and to provide means for securing a raised car to the frame.

A further object is to provide a locking device for the pivoted frame and means for automatically releasing the lock as the car becomes secured to the frame.

Other objects of the hoisting moving and dumping mechanism will appear in the following specification.

A still further object of this invention is to provide a car which is especially equipped to cooperate with the aforesaid mechanisms and to make a combination of such a hoisting and dumping arrangement and such a car as will be set forth fully hereinafter.

Referring to the drawings,

and

Like characters of reference designate corresponding parts on each side of the figures.

Ill designates the body of an ordinary electric mine locomotive mounted on wheels II' which in this case are flanged and arranged to run on rails I2. The motors are not shown but they may be directly geared to the wheels or connected therewith by a drive chain. I4 is a large gear affixed in a horizontal position to the top of the body I0. I5 is a turn-table supported above gear I4 by anti-friction bearings I6.

Supported on the turn-table is a main frame comprising parallel side members 20 and a plurality of transverse members 2I, 22, 23, 24, 25, 26 and 2l. Two of the frame members, 24 and 25, rest upon and are affixed to the turn-table I5. 5 A counterweight 58 is on one end of this frame.

3B is an electric motor mounted upon a shelf 3l below the main frame. It is connected to drive ropes or cables 32 which run alternately under and over grooved sheaves 33, 34, 35 and 36 mounted upon shafts which run between the transverse members 22 and 23 of the main frame and are kept in driving tension therewith by a cable tightener 3'! which is pulled downwardly by a spring 38. Aflixed to the shafts of the grooved 15 sheaves are friction pulleys 43, 44, 45 and 46.

50 is a friction pulley between the pulleys 43 and 44. It is mounted upon an eccentric bushing, the angular position of which may be shifted by a lever 5I, to bring pulley 50 into driving engagement with either pulley 43 or 44. Affixed to the shaft of pulley 50 is a rope sheave 52. A rope or cable 53 runs over sheave 52 and similar sheaves 54, 55 on threaded parallel shafts 56 and 5l. 58 is a weight or a receptacle which may be 5 weighted, supported by and in threaded engagement with the shafts 56 and 51.

When the pulley 50 is moved into driving engagement with pulley 43 the threaded shafts 56 and 51 will be driven in one direction by the con- 30 nections thus described. When the pulley 50 is moved into driving engagement with pulley 44, shafts 56 and 51 will be driven in the opposite direction. Thus, by a movement of lever 5| the weight or receptacle 58 will be moved toward or away from the end of the main frame to vary its counterbalancing effect.

60 is a friction pulley between the pulleys 44 and 45. It may be moved into driving engagement with either of them by a manipulation of 40 a lever tIv to cause its shaft 62 to be driven in one direction or the other. Shaft 62 is arranged to actuate the car raising and dumping mechanism which will be described later.

'I0 isa friction pulley between the pulleys 45 45 and 46. It may be moved into driving engagement with either of them by a manipulation of lever 'II to cause its shaft 'I2 to be driven in one direction or the other. 'I5 is a worm on shaft 'I2 in mesh with a gear I'I which is on a shaft with a pinion 'I8 which is engaged With the large gear I4 on the body I0. This arrangement enables the operator to rotate the main frame around the axis of the gear I4 in either direction.

A secondary frame is pivotally mounted in the 55 end of the main frame opposite the counterweight 58. It comprises parallel side members connected at their ends by transverse members 8| which are centrally supported on bearings 82 in the transverse members 26 and 21 of the main frame. This secondary frame is in a part of the main frame which extends beyond the body |0 of the locomotive.

83, 83 are parallel shafts in bearing 84, 84 in the tr-ansverse members 8|. On each of these shafts are two chain gears 85 and a bevel gear 8B. The latter mesh with bevel gears 53 on the ends of a shaft G4 in bearings on one of the transverse members 8|. In the center of shaft 64 is a gear 65 which is in mesh with a worm 66 on the end of shaft 62.

It is evident that the operator may, by manipulation of the lever 6| and the mechanism previously described, cause the shaft 64 to be driven in either direction.

81, 81 are chains, one end of each of which is ailxed to one of the chain gears 85, and the other ends of which are connected to lifting rods 88. It may be seen that when the chain gears are in the positions in which they are shown in Fig. 3, the lifting bars 88 will hang directly under the shafts 83.

90 is a flat car having wheels 9| adapted to run on the tracks |2. The body of the car overhangs the wheels and forms shoulders 92 which are to be engaged by the lifting rods 88. 93 are lugs at the outer edges of the shoulders. 94 are parallel sided bumpers at the ends of the car. On the transverse members 8| of the secondary frame are guides 95 into which the car bumpers 94 t when the car is raised. Angle irons 98 run across between the guides to limit the upward movement of the car.

|00 is a lock horizontally pivoted in a bracket in one of the transverse members 8| of the secondary frame. On one side of the bracket the lock extends downwardly, as at |0|, and rearwardly, as at |82, through an opening in transverse member 8| and into a socket in the transverse member 26 of the main frame. 'Ihis locks the secondary frame against rotation relative to the main frame. The other end of the lock extends forwardly, as at |03, and downwardly, as at |04, beyond and below the angle iron 96. When the car 90 is raised to the position in which it is shown in Fig. 5, its bumper engages and lifts the end |04 of the lock and rocks it to remove its end |02 from engagement with the m-ain frame.

I will now describe the operation of the apparatus. The locomotive and/or a loaded car are moved on the track until they are in the relative positions shown in Figs. 1, 2 and 3. Shafts 83 are then turned in opposite directions to cause the chain gears 85 to rotate in the directions indicated by the arrows in Fig. 3. The rst effect of this rotation is to move the lifting bars 88 into the positions indicated at 88A (Fig. 3), under the shoulders 92 of the car and inside the lugs 93. Further rotation of gears 85 will cause the chains 81 to be wound up on them to lift the car. The gears 85 are iianged to receive the chains.

During this part of the operation the position of the weight 58 is shifted to counterbalance the weight of the car and its load.

As soon as the bumpers 94 of the car are within the guides 95, the rotation of shafts 83 is stopped. Then the main frame is rotated about the axis of large gear |4 until the car 90 is over -a desired point relative to the track I2. Further rotation is then imparted to shaft 83 to lift the car until its bumpers engage the angle irons 90. The car is then secured firmly to the secondary frame. As the car nears its final upward position, one of its bumpers 94 lifts the end |00 of the lock and moves its end |82 out of engagement with the transverse member 26. Further rotation of shaft 82 will thereafter be imparted to the secondary frame and to the car on it. This movement may be continued until the secondary frame and the car have been turned over to dump its load, and then reversed until they reach their initial position. Or, if desired, they may be rotated 360 to their initial position.

After the car has been dumped the main frame may be rotated back to its initial position and the car lowered to its initial position on the track, or it may be rotated 180 from its original position and the car lowered onto the track on the other side of the locomotive.

The mechanisms shown and described are for illustrative purposes only, as changes and structural modifications may be made within the spirit and scope of the invention and I intend no limitations other than those which are imposed by the appended claims.
